    LLM Wiki

A pattern for building personal knowledge bases using LLMs.
This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.
The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Vue.filter('formatNumber', function (value, decimals = 2, thousandsSeparator = ',') {
    let result = parseFloat(value).toFixed(decimals).toString();
    if(thousandsSeparator) result = result.replace(/\B(?=(\d{3})+(?!\d))/g, thousandsSeparator)
    return result
});

                How to export and import gpg keys
              
          
    Every so often I have to restore my gpg keys and I'm never sure how best to do it.  So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.
Method 1

Gotten from the RedHat GPG migration manual
Backup the public and secret keyrings and trust database

## Export all public keys

gpg -a --export >mypubkeys.asc

                How to proxy web apps using nginx?
              
          
    Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
